+## Result Analysis
+
+### Interactive Dashboard
+
+For comprehensive analysis and visualization of benchmark results, use the included **Performance Dashboard** - a web application designed for IPC performance analysis:
+
+```bash
+# Start the interactive dashboard
+python utils/dashboard/dashboard.py --dir /path/to/results --host 0.0.0.0 --port 8050
+```
+**Analysis Workflows:**
+- **Summary Analysis**: Performance overview cards, head-to-head comparisons, and statistical breakdowns
+- **Time Series Analysis**: Temporal patterns, anomaly detection, and moving averages with 5 preset configurations
+- **Interactive Exploration**: Filter by mechanism/message size, drill down into specific test runs
+
+**Key Features:**
+- **Advanced Visualizations**: Interactive time-series plots, statistical overlays, and comparative analysis
+- **Intelligent Insights**: AI-powered performance recommendations and mechanism comparisons
+- **Modern UI**: interface with preset configurations for different analysis scenarios
+- **High Performance**: Handles millions of data points with threaded processing and smart caching
+- **Export Capabilities**: Generate reports and capture insights for documentation
+
+The dashboard automatically discovers all JSON and CSV output files in your results directory and provides powerful tools for understanding IPC performance characteristics across different scenarios.
+
+For detailed dashboard documentation and setup instructions, see [`utils/dashboard/README.md`](utils/dashboard/README.md).

+# Rusty-Comms Performance Dashboard
+
+A high-performance interactive web dashboard for analyzing Inter-Process Communication (IPC) benchmark results. Features modular architecture, advanced visualizations, and intelligent performance analysis.
+
+## 🚀 **Quick Start**
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Start dashboard
+python dashboard.py --dir /path/to/benchmark/data --host 0.0.0.0 --port 8050
+```
+
+Access at: `http://localhost:8050`
+
+## 📊 **Key Features**
+
+### **Summary Analysis**
+- **Performance Overview**: AI-generated insights and key metrics cards
+- **Head-to-Head Comparisons**: Interactive comparison matrices for P50/Max latency
+- **Statistical Analysis**: Comprehensive latency and throughput breakdowns
+- **Data Tables**: Sortable pivot tables for one-way vs round-trip performance
+
+### **Time Series Analysis**
+- **Interactive Visualizations**: Real-time scatter plots with advanced controls
+- **5 Preset Configurations**: Performance, detailed inspection, statistical, outlier detection, and reset modes
+- **Statistical Overlays**: Moving averages, percentile bands, anomaly detection
+- **Anomaly Detection**: ML-based (Isolation Forest) and statistical (IQR) methods
+- **Smart Sampling**: Multiple strategies for large datasets (8M+ records)
+
+### **Advanced Features**
+- **Interactive File Browser**: Rich file explorer replacing simple dropdown
+- **Threaded Processing**: Concurrent loading with 8 workers for optimal performance
+- **Enhanced Caching**: TTL-based cache with LRU eviction (10min TTL, 50 items)
+- **Professional UI**: Dark theme with neon accents and responsive design
+
+## 🏗️ **Architecture**
+
+### **Modular Design**
+- **`cache.py`** - Caching layer with decorators and TTL management
+- **`data_processor.py`** - Data discovery, loading, and processing logic
+- **`dashboard.py`** - Main UI application and visualization components
+- **`dashboard_styles.css`** - External CSS styling
+
+### **Performance Optimizations**
+- **Concurrent Processing**: ThreadPoolExecutor for file loading (8 summary, 6 streaming workers)
+- **Memory Efficient**: Handles millions of records with pandas optimization
+- **Smart Caching**: 70-90% cache hit rate for repeated analyses
+- **Data Sampling**: Adaptive strategies for large dataset visualization
+
+## 📈 **Performance Metrics**
+
+| Operation | Time | Details |
+|-----------|------|---------|
+| **Startup** | 5-15s | Depends on data size |
+| **Summary Analysis** | 8-12s | Full statistical processing |
+| **Time Series** | 3-8s | Varies by sampling strategy |
+| **Memory Usage** | 200-500MB | For typical datasets |
+
+## 📁 **Data Format**
+
+### **Auto-Discovery**
+The dashboard automatically discovers files in your data directory:
+
+- **Summary**: `*_results.json` - Statistical summaries and throughput data
+- **Streaming**: `*_streaming.json` or `*.csv` - Raw latency measurements
+- **Mixed Formats**: Supports both JSON and CSV in the same directory
+
+### **Sample Structure**
+```json
+{
+ "mechanism": "SharedMemory",
+ "message_size": 1024,
+ "one_way_latency_us": 1.23,
+ "round_trip_latency_us": 2.46,
+ "one_way_msgs_per_sec": 812347.5,
+ "round_trip_msgs_per_sec": 406173.75
+}
+```
+
+## 🎛️ **Configuration**
+
+### **Command Line Options**
+```bash
+python dashboard.py [OPTIONS]
+
+Options:
+ --dir PATH Data directory (required)
+ --host HOST Bind address (default: 127.0.0.1)
+ --port PORT Port number (default: 8050)
+ --debug Enable debug mode (default: False)
+```
+
+### **Interactive Controls**
+- **Mechanism Filtering**: Multi-select IPC mechanisms
+- **Message Size Filtering**: Select specific byte sizes
+- **File Browser**: Navigate and select data directories
+- **Analysis Presets**: Quick configuration templates
+- **Real-time Updates**: Dynamic chart regeneration
+
+## 🔧 **Technical Requirements**
+
+### **Dependencies**
+- Python 3.9+
+- Dash 3.2.0+
+- Plotly 5.24.1+
+- Pandas 2.2.3+
+- NumPy 2.1.1+
+- Scikit-learn (optional, for ML anomaly detection)
+
+### **Browser Support**
+- Chrome/Edge 90+
+- Firefox 88+
+- Safari 14+
+
+## 🐛 **Troubleshooting**
+
+### **Common Issues**
+
+**Dashboard won't start:**
+```bash
+# Check Python version and dependencies
+python --version && pip list | grep dash
+
+# Verify port availability
+lsof -i :8050
+```
+
+**Performance issues:**
+- Large datasets may require additional memory
+- Use data filtering for initial analysis
+- Check browser console for JavaScript errors
+
+**Data not loading:**
+- Verify JSON/CSV file formats
+- Check directory permissions
+- Review terminal logs for error messages
+
+## 🤝 **Contributing**
+
+The dashboard is part of the [Rusty-Comms](../../README.md) benchmarking suite. Contributions welcome for:
+
+- Additional visualization types
+- Enhanced statistical analysis
+- Performance optimizations
+- New data format support
+
+## 📊 **Example Workflow**
+
+1. **Start**: `python dashboard.py --dir ./results`
+2. **Browse**: Use interactive file browser to select data
+3. **Filter**: Choose mechanisms and message sizes
+4. **Analyze**: Review summary insights and comparisons
+5. **Deep Dive**: Switch to time series for temporal analysis
+6. **Configure**: Apply presets or custom visualization settings
+7. **Export**: Capture charts and insights for reporting
